Abstract

Trigeneration systems should be designed to supply all energy demands of a new facility and increase the profit of an existing facility. In this paper, a model to determine optimum capacity of trigeneration systems that maximizes the present value of the net profit hasbeen developed to embed trigeneration systems to existing systems. Proposed economical model has been employed on a university campus. Considering the electricity, heat and chilling demand of the campus and the characteristics of existing system, optimum trigeneration capacity and operation strategy has been defined.

Key words: Economical model, operation strategy, trigeneration system.
